Expected Functionality: We expect to be able to apply up to 60V DC input and regulate out to +12V using the LT8390
Issue:When voltages > 17.5V are applied to the input (+VBATT), the output of the LT8390 begins to oscillate. At input voltages < 17.5V the…
I am trying to simulate the LT8390 using LTSPICE, however I want to use a solar panel as an input. I managed to simulate a solar cell, however I cant use it as an input into the LT8390 model. I am trying to model and simulate the scenario on page…
Please use the equations provided on the "Programming Output Voltage and Thresholds " section of the datasheet of LT8390 to change the output voltage
Yes it is possible to use a solar cell as an input for LT8390
I have a problem with the LT8390, I use it as a solar charger with a lead acid battery 12V.
I use your application circuit showing a solar panel charger in datasheet page 32.
The layout is made as specified in datasheet.
The FB circuit is a little…
I'm using ic LT8390 in buck region with: Input 36V (This value is output voltage of ic LT8705) and output which I need is 24V. But, output voltage of LT8390 is oscilated, and volatage value is not 24V. If I use input is lower 30V, output voltage…
Use LT8390 to make a 24V input, 12V/25A output power supply, encountered some problems during debugging
Adjust the output current up to 8A, more than 8A for a while, the inductor will emit a noise, the circuit at this time no output.
1. My inductor model…
Please use the article below as reference:
Some highlight that could be taken on the article is to tie the IMON pin on the master…
I am trying to simulate the LT8390 using LTSPICE, I am trying to model and simulate the scenario on page 32 of the LT8390 data sheet (125 W Solar panel to 12V battery charger). I have built the model as per the datasheet, I used a voltage source as…
LT8390 behavior would indeterminate. If left floating the potential on the Sync/Sprd could be affected by several external factors such as EMI/EMC which makes the behavior unpredictable for this case.
